Hi, 89irocz....there's no text in the reply..

Sometimes if wish this forum had a SPELL CHECK option before you post...

Anyway, you could easily reset the brake light using the same process to reset the other warning lights. Disconnect the negetive battery cable for 5 minutes.

If the brake light still continues to come on, That could indicate a problem with the stock proportioning valve. Simple disconnect the harness and try reseting the computer again. If all else fails, check your fuses. There are not any sensors on or neer the pads or rotors on these cars. Happy hunting.

The computer has nothing to do with brake lights. The brake lights are controlled by a simple switch above the brake pedal.

I have rear discs.
Had a brake warning light that remained on after I did a brake job that was so complete, it also included bleeding. Nothing would reset that darn light.
I pulled the front calipers, used a 'C' clamp to push in both pistons all the way.
Reassembled. Hit pedal, and light went out.
I am certain that this won't help you, but there is always a chance that I am wrong.

NoTransistors,
This is because there is a pressure switch on the proportioning valve. If there is a leak in the lines or a large amount of air in the lines it will trip this switch and the brake light on your dash will stay on.

So why has it reset and stayed that way? Do I still have a problem? The car actually does stop, and I am happy to say that this is now in a straight line. Before the rebuild, it pulled dramatically with warmed brakes.

From my experience, this means either the brake system needs to be bled better or that the warning switch is bad. Even with some air in the lines, in a lot of cases the car will still stop ok. (Like mine did for a while.) But you need to find the real cause to make sure. I would start with bleeding the lines or having a shop do it.

In any case, the warning light is supposed to turn off once the switch (and system) senses a particular pressure. (Something like 400 PSI, if I remember right. Someone keep me honest.)

Hope this helps.

Thanks for your reply.
